Benefits of technology

The present patent describes an XYZ flexural mechanism that allows for smooth, frictionless motion in axial directions relative to a motion stage platform. The mechanism includes a first voice coil actuator, a first flexural bearing, and a motion stage platform; a second voice coil actuator, a second flexural bearing; a third voice coil actuator, and a third flexural bearing. Each voice coil actuator includes a linear motor, a piston, a magnet, and a voice coil. The frame supports the XYZ flexural mechanism and each flexural bearing supports the motion stage platform in an orthogonal direction. The technical effect of the patent text is an improved mechanism for smooth and frictionless motion in the axial directions relative to a motion stage platform.

Problems solved by technology

When it comes to scanning or determining a position of an object in the X, Y, and Z directions, many of the present instruments have a limitation for the precision that can be obtained by the process used for scanning purposes.
In addition, other present instruments are relatively costly.

Abstract

An XYZ flexural mechanism comprising an X-axis flexural mechanism comprising a first voice coil actuator, a motion stage platform, a plurality of flexural bearings, and a plurality of guide rods, a Y-axis flexural mechanism comprising a second voice coil actuator, a plurality of flexural bearings, a plurality of guide rods, and a frame, and a Z-axis flexural mechanism comprising a third voice coil actuator, a plurality of flexural bearings, a plurality of guide rods, and a frame, the frame supporting the XYZ flexural mechanism.

Description

RELATED APPLICATIONS[0001]The present disclosure is related to and claims priority to U.S. Provisional Application No. 62 / 609,325, filed Dec. 21, 2017, entitled “POSITION DETERMINING SYSTEM,” the entire disclosure of which is hereby expressly incorporated herein by reference.FIELD OF DISCLOSURE[0002]The present disclosure relates generally to a position determining system. In particular, the present disclosure relates to a high precision position determining system including a sensor-less XYZ flexural mechanism.BACKGROUND OF DISCLOSURE[0003]When it comes to scanning or determining a position of an object in the X, Y, and Z directions, many of the present instruments have a limitation for the precision that can be obtained by the process used for scanning purposes. In addition, other present instruments are relatively costly. Thus, it would be beneficial to have a positioning system capable of very precise scanning that is not overly expensive. The position determining system of the ...
